Title: Optical elements and systems
IPC: G02B21/14
Filed: 1974-01-16
Abstract: 1410902 Polarizing interferential systems AMERICAN OPTICAL CORP 16 Jan 1974 [16 Jan 1973] 02125/74 Heading G2J A polarizing interferential system with a light source, polarizer, compensator, object, beamsplitter and analyzer on a centre line has the compensator as a single birefringent crystalline first wedge with an optic axis and with two converging planar surfaces intersecting the centre line, the beam-splitter as a single birefringent crystalline second wedge with an optic axis and with two converging planar surfaces intersecting the centre line, the wedges being arranged to have at least three of the group, comprising the planar surfaces and optic axes, are oblique to the centre line. The system may be applied to study of optical characteristics of objects by differential interference or phase contrast by transmitted or reflected light e.g. in microscopes. A condenser in combination with an objective must focus the fringe plane of the compensator into the same plane, in the same direction and with the same magnification as the fringe plane of the beam-splitter. By tilting a wedge or rotating the optic axis with respect to the wedge surfaces, the fringe plane may be displaced in the desired position, e.g. coinciding or near to the back focal plane of the objective. The drawings accompanying the Specification show ten ways in which the wedges or the optic axes of the wedges may be orientated, with in each case the optic axis of one of the wedges parallel to the apex of the wedge. The wedges may be facially coupled on one or both planar surfaces with a non- refringent glass wedge.

Title: Improvements in the purification of chlorine
IPC: C01B7/07
Filed: 1937-01-25
Abstract: <PICT:0467803/III/1> Chlorine containing less than about 1 per cent of organic impurities is purified by treatment in the gas phase with liquid chlorine in which the impurities are condensed and dissolved. The impure liquid chlorine may be subsequently freed from the organic material.  For example, impure chlorine is passed upwardly through a column 1 suitably constructed to ensure intimate contact between gas and liquid, and a portion of the chlorine, e.g. about 15 per cent by weight, is liquefied by means of the refrigerating pipe 9.  In its descent of the column, the liquid chlorine absorbs the impurities from the gas stream and an impure liquid collects at the base of the column, from which the chlorine is driven off by a steam jacket 2. Pure gaseous chlorine leaves by pipe 7, which may be situated below the refrigerating pipe 9. The organic impurities when accumulated are driven off by gas pressure through the drain 5 or directly through the drain 4. Chlorine containing other gaseous diluents, e.g. air, hydrogen or carbon dioxide, may be thus purified and the gaseous diluents may be subsequently removed, e.g. by liquefaction.
Patent GB-729353-A (GB)
Title: Process for fixing, in continuous production, dyes on cloth and device therefor
IPC: D06B19/00
Filed: 1953-01-26
Abstract: <PICT:0729353/IV (c)/1> A continuous process for fixing dyes on cloth comprises impregnating the cloth with the dye or with the dye and a reducing agent and passing the cloth between a heated surface and a heat-retaining apron so that the steam emitted produces a reaction and fixes the dye on the cloth.  The Figure shows an apparatus for dyeing cloth Ti which has been impregnated with dye in either the liquid or pigmentary state and if necessary with a reducing agent. The cloth passes over roller D6 and over the greater part AEG of the surface of a stainless steel rotating drum T the surface of which is heated for example to a temperature of 50-110 DEG  C.  The drum is surrounded by an endless heat-retaining blanket B of rubber or plastic material which is wider than the band of cloth Ti and fits tightly over it, so that the heat supplied by the heated wall of the drum causes steam to be generated from the water which is contained in the dye liquor and the required thermo-chemical reaction resulting in the fixing of the dye takes place.  The cloth Ti after passing over the drum T passes round the roller D1 and is fed to known washing and soaping apparatus.  The heat-retaining blanket is cleaned by the rotating cylindrical brush L and is dried by the heater R. The speed of rotation of the roller and the temperature to which the surface is raised may be adjusted, thus varying the duration of the process and the treatment temperature.

Title: Alternating current electromechanical transducer and method of constructing same
IPC: H01F29/02
Filed: 1962-01-23
Abstract: 968,231. Transformer arrangements. BECKMAN INSTRUMENTS Inc. Jan. 23, 1962 [Feb. 9, 1961], No. 2382/62. Heading H2H. An A.C. transducer having a low output impedance and reduced quadrature voltage and linearity errors is constructed by connecting equally-spaced taps 13A ... 25A on the winding 12 of an autotransformer 10 to similarly-placed taps 13P ... 25P on the resistance element 26 of a precision multi-turn potentiometer 11 having a movable wiper contact 27. The autotransformer may comprise a toroidal core mounted on a rotary potentiometer and concentric with its shaft, Fig. 2 (not shown). The output impedance and voltage and linearity errors may be further reduced by increasing the number of taps, and any desired input impedance may be obtained by the choice of an auto-transformer and potentiometer having suitable impedance values. Linearity errors caused by incorrect placing of the intermediate taps may be reduced by moving individual taps on the autotransformer or the potentiometer or both, such movement of the transformer taps being similar to that described in co-pending Application No. 2378/62. Linearity errors caused by " end resistances " Ra, Rb (Fig. 9), may be obviated by connecting the input terminals 57, 58 to taps 65, 66 displaced a required distance from the ends of the autotransformer winding, but in practice it is preferable to extend each end of the winding the required distance beyond the input terminal and connect each extension to the corresponding end of the potentiometer, so that the taps between the input terminals remain equally spaced. The operating characteristics of a typical A.C. transducer constructed as described above and of a typical potentiometer when used alone are discussed and illustrated, Figs. 3, 6 and 7 (not shown). The transducer may be made non- linear by unequal spacing of the taps on the autotransformer and potentiometer. One or more outputs may be made 180 degrees out of phase with the input over any desired portion of the potentiometer by positioning the fixed output tap of the potentiometer to a position other than the end of the resistance element or by rearranging the interconnecting leads between the autotransformer and potentiometer (or by a combination of both of these methods).

Abstract: 1408325 Reversing BURMEISTER & WAIN'S MOTOR-OG MASKINFABRIK AF 1971 A S 18 Jan 1973 [27 Jan 1972 22 Dec 1972] 2732/73 Heading F1K The direction of rotation of a two-stroke I.C. engine for marine use, is reversible by angularly adjusting the cam-shaft relative to the engine crank-shaft to which it is coupled via a sprocket 7 connected to the cam-shaft by a pair of crank throws 12 journalled at 11 in sliding shoes 10 in the sprocket 7 and at their ends 14 connected to the piston vanes 17 of hydraulic rotary motors 18. As shown, the motors 18 are mounted in radial arms 5 of a driver 3 fast with a shaft 1 for coupling with the cam-shaft. The driver 3 has radial arms 6 to support the opposite ends of the crank throws 12. The sprocket 7 has radial guideways 9 supporting the shoes 10. Oil from a lubricating oil pump (60), Fig. 5 (not shown), is fed via lines 42, 43 and inside and outside of a tube 29 in a bore 30 in the shaft 1 selectively to radial bores 32, 33 and circumferential grooves 34, 35 to opposite sides of the vane pistons for forward and reverse. The control circuit includes a pneumaticallyactuated four-way valve (57) connecting lines 42, 43 selectively to the oil pump (60) via a non-return valve (59) or via a non-return valve (63), a throttle valve (62) and a reducing valve (64) which, together with an overflow valve (66), maintains a minimum pressure on the non-operative side of the piston vane. A pneumatic-hydraulic pressure converter (48) provides a higher hydraulic pressure in lines 42, 43 than the pump 60 delivery pressure. Lines (21), (22) into the motors 18 provide damping of final piston movement. A sleeve 46 threaded on a ring 45 fast with the shaft is connected to sprocket 7 so that relative rotation between the sprocket and shaft causes the sleeve 46 to move axially. This axial movement may be utilized to indicate the relative angular position of the cam-shaft and crank-shaft.  In an alternative embodiment, Fig. 6 (not shown), the two crank throws are inter-connected for synchronism by gears (80), (81) respectively fast with the crank throws and the sleeve 46. Spring-loaded shock absorbers may be mounted on sprocket 7 for abutment by arms 5 or 6. In a further alternative, the hydraulic motors may be formed in the sprocket, and the guideways in the arms 5 or 6.
